Low volume short duration high-intensity interval training and repeated sprint ability in Gaelic football players
Kelly, David
Gaelic Football is the most popular sport in Ireland and is characterized by irregular changes of pace and high-intensity efforts interspersed with periods of light to moderate intensity activity. Speed, power and aerobic capacity are essential fitness components for optimal performance during match play. A high level of aerobic conditioning is required to generate and maintain power output during repeated high intensity activities. Study 1: Anthropometric, physiological, metabolic and endurance exercise performance were evaluated in club level Gaelic football players (n=15) in response to 2 weeks of low volume short duration high-intensity interval training (LS-HIT) or high volume endurance training (HVET). Six sessions of LS-HIT and HVET induced similar improvements in endurance exercise performance. V̇O2max was increased significantly in the LS-HIT group only. There was no change in running economy or vV̇O2max following LS-HIT or HVET. Study 2: This study compared the effect of 6 weeks of LS-HIT and HVET on anthropometric, physiological, metabolic and performance indices in club level Gaelic football players (n=25). Both groups had a similar significant increase in V̇O2max, vV̇O2max, Wingate anaerobic performance and endurance exercise performance. Running speed and jump performance did not change following LS-HIT and decreased significantly in response to HVET. Study 3: The construct validity and determinants of repeated sprint ability (RSA) tests were evaluated in club and county level Gaelic football players (n=30). The RSA test involving 8 maximal 30 m sprints on a 22.5 sec cycle demonstrated construct validity. The ability to perform repeated sprints has a greater relation to running speed and power and blood lactate levels than indices of endurance performance. Conclusion: LS-HIT is a time efficient strategy to induce aerobic adaptations normally associated with traditional HVET and maintain indices of speed and power in club level Gaelic football players. An RSA test involving 8 x 30 m sprints on a 22.5 sec cycle was superior in county than club level Gaelic football players.
